Help with the Start Button and pins

slmarcotte opened this issue · 0 comments

Looking for some help.
First of all this is a very nice piece of code.
I'm confused about the use of Pins 16 and 18 for the start button.

Wouldn't the pin go to one terminal of the switch and the other button terminal to ground?

If so then what is the other pin used for?

Thank you
